Robert Hooke
Explanation:
Answer:
Robert Hooke is the first person
Explanation:
Robert Hooke made his own microscope, which he made himself, and observed some small pieces of cork underneath it. This is where he fist viewed and named the cells.

a. At what speed was Brandon flying?
b. What was his velocity?
2. Use the graph to answer the questions.
Answer:
a. Bradon was flying at the speed rate of 350 miles/hour.
b. His velocity is 350 miles/hour due west.
Explanation:
The speed of an object is the ratio of distance moved to the time taken, while velocity is the ratio of displacement to time taken. The major difference between speed and velocity is that speed is a scalar quantity, while velocity is a vector quantity.
Vector quantities are described by both magnitude and direction, while scalar have only magnitude.
From the question,
distance = 700 miles and time taken = 2 hours
a. speed =
=
= 350 miles/hour
∴ Bradon was flying at the speed rate of 350 miles/hour.
b. velocity =
displacement = 700 miles of west, time taken = 2 hours
velocity =
= 350 miles/hour due west
His velocity is 350 miles/hour due west.

time. It consists of two flasks, one inside the other, that connect at the neck. The space between the two
flasks is completely empty of air.
Q-Why does the design of the vacuum flask minimize heat transfer by conduction?
A)- One flask is smaller than the other flask.
B)- One flask is more reflective than the other flask.
C)- There is no air between the two flasks.
D)- The two flasks do not touch each other, except at the neck.
Answer is: C) There is no air between the two flasks.
Heat in this example can transfer throw thermal conduction.
Because there are no mo molecules to transfer heat, there is no conduction.
Thermal conduction is the transfer of heat through physical contact. Thermal conduction is the transfer of heat by microscopic collisions of particles. Heat spontaneously flows from a hotter to a colder body.
The process of heat conduction depends on four basic factors: the temperature gradient, the cross section of the materials involved, their path length and the properties of those materials.
Because there are no mo molecules to transfer heat, there is no conduction.
